Friction Stir Superplasticity for Unitized Structures

A volume in the Friction Stir Welding and Processing Book Series

By: Zongyi Ma,Rajiv S. Mishra

This book describes the fundamentals and potential applications of 'friction stir superplasticity for unitized structures'. Conventional superplastic forming of sheets is limited to the thickness of 3 mm because the fine grained starting material is produced by rolling. Friction stir superplasticity has grown rapidly in the last decade because of the effectiveness of microstructural refinement. The thickness of the material remains almost constant, and that allows for forming of thick sheets/plates, which was not possible before. The field has reached a point where designers have opportunities to expand the extent of unitized structures, which are structures in which the traditional primary part and any supporting structures are fabricated as a single unit. With advanced optimization and material considerations, this class of structures can be lighter weight and more efficient, making them less costly, as well as mechanically less complex, reducing areas of possible failure. - Discusses how friction stir processing allows selective microstructural refinement without thickness change - Demonstrates how higher thickness sheets and plates can be superplastically formed - Examples are presented for aluminum, magnesium and titanium alloys - Covers the production of low-cost unitized structures by selectively processing cast sheets/plates

Investing in Human Capital for Economic Development in China

By: Gordon G. Liu,Shufang Zhang,Zongyi Zhang

This book is a reflection of the current research that explores the mechanism, dynamics and evidence of the impact of human capital on economic development and social well-being in modern China. Composed of keynote speeches and selected papers from The 2005 International Conference of the Chinese Economists Society (www.china-ces.org), it tracks the latest understanding and empirical evidence of the relationships amongst health, education and economic development in China. The book presents a broad spectrum of study topics covering human capital and economic growth; demand, attainment and disparity in both education and health; and investing in human capital and the economic and social returns in China. Distinguished contributors include Robert Fogel, Michael Grossman, Daniel Hamermesh, Gregory Chow and Dean Jamison.

Knowledge, Content, Curriculum and Didaktik

Beyond Social Realism

By: Zongyi Deng

Bringing to bear a wealth of literature from curriculum theory, Didaktik, philosophy of education and teacher education, this book broadens and enriches the conversation initiated by Michael Young and his colleagues on 'bringing knowledge back in' (Young, 2007). Knowledge, Content, Curriculum and Didaktik is distinctive in providing a comprehensive and multifaceted analysis of the role of knowledge, and in particular curriculum content, in relation to curriculum policy, curriculum planning and classroom teaching. It makes a case for linking knowledge and content to the development of human powers or capabilities needed for the 21st century and unpacks the challenges for curriculum policy, curriculum planning and classroom teaching. The book discusses, among other issues: Educational aims and theories of knowledge School subjects and academic disciplines: differences and relationships School subjects and theories of content Understanding the content for teaching The book will be relevant for scholars, researchers, policy makers and curriculum developers who seek a more sophisticated, more balanced and philosophically better grounded understanding of the role of knowledge and content in education and curriculum.
